Mri-pet cephalic molecular imaging coil and mri-pet cephalic molecular imaging system

Abstract

This invention discloses an MRI-PET cephalic molecular imaging coil and an MRI cephalic molecular imaging system including this MRI-PET cephalic molecular imaging coil; the said MRI-PET cephalic molecular imaging coil is an integrated and nested structure, with a molecular signal acquisition assembly installed on the peripheral surface of the MRI cephalic RF coil, the said molecular signal acquisition assembly including a crystal gamma-ray detector and photoelectric conversion structure; the said photoelectric conversion structure is semi-conductors, having an effect in preventing the impact of magnetic field on gamma-ray imaging, hence making it possible to obtain precision fusion images of magnetic resonance and molecular imagery and ensuring consistency of physiological and biochemical information in spatial location and temporal synchronization.

Description

TECHNICAL FIELD OF INVENTION[0001]The present invention relates to the field of nuclear magnetic resonance analysis and nuclear medical imaging, and more particularly, to an MRI-PET cephalic molecular imaging coil and a system including the said MRI-PET cephalic molecular imaging coil.TECHNICAL BACKGROUND[0002]Given the extensive application of nuclear magnetic resonance imaging (MRI) in basic research such as chemistry and biology and also in clinic medicine and pharmaceutical R&D, many kinds of high resolution nuclear magnetic resonance analysis techniques have become an important tool in biochemistry research. With the rapid development of transmission imaging on the structurology and anatomy, the physiological and biochemical information imaging also becomes an important component. At present, the more advanced technology of fusion-imaging with information of anatomy structure and physiological biochemistry has been developed in field of science and clinic, this technology has i...

Benefits of technology

[0013]At present, the molecular imaging MRI is the most advanced medical imaging technology in the world, and the combination of PET and MRI is an example, which includes separated type and integrated type. However, such equipment has huge space volume and expensive price. The technical scheme of the present invention provides for a nested structure and compact equipment, making it possible to be directly arranged in the access hole of the available MRI to acquire the MRI image and molecular image simultaneously at the same space. Therefore, it is able to synchronously acquire molecular MRI images on the same machine. Because images are generated under the same condition and state, the imaging information could be more precise and more objective for clinic studies and scientific research and the clinic results would be better and more precise. Additionally, the system or coil of the present invention is compatible directly with MRI equipment of the existing technology and its dimensions or sizes render it possible to be inserted in the existing MRI access holes. As a result, the equipment of the present invention is cost-effective and does not need extra civil works or machine rooms, greatly reducing the investment and increasing the utilization rate. Particularly, MRI now has been extensively applied in hospitals, so the equipment of the present invention can be directly used with the existing MRIs in hospitals, and therefore, it is greatly saved in manpower, material and financial resources.

Problems solved by technology

The method has many disadvantages, however, such as huge volume and expensive price.

In addition, the limitation of the current technology is the problem of acquisition accuracy, which is caused by has separated scanning of PET and MRI.
